Environmental pollution and the shortage of drinking water are the challenges that mankind is facing. Solar interface evaporation technology has been demonstrated as an important method for producing clean water, but its application to sewage still faces problems, mainly manifested in solubility and oily pollutants. Therefore, an evaporator device contains a superhydrophobic BiWO felt floating layer, a filter paper hydrophilic layer, and a copper foam/CuO photothermal layer, of which the water contact angle of the superhydrophobic felt can reach 159°. The floating layer not only has the ability to adsorb -hexane but the Rh B degradation can also be realized under indoor/outdoor light conditions. The carrier life of BiWO is 28.8 ns. A copper foam/CuO photothermal layer prepared through a low-temperature treatment is combined with the floating and hydrophilic layer to obtain an evaporation rate of 1.53 kg m h.
环境污染和饮用水短缺是人类面临的挑战。太阳能界面蒸发技术已被证明是生产清洁水的重要方法，但将其应用于污水仍面临问题，主要表现为溶解度和油性污染物。因此，一种蒸发器装置包含一个超疏水 BiWO 毡漂浮层、滤纸亲水层和铜泡沫/CuO 光热层，其中超疏水毡的水接触角可达 159°。漂浮层不仅具有吸附正己烷的能力，而且在室内/室外光条件下也可以实现 Rh B 的降解。BiWO 的载体寿命为 28.8ns。通过低温处理制备的铜泡沫/CuO 光热层与漂浮和亲水层相结合，获得 1.53kg·m h 的蒸发率。
